Abstract

In this paper, a multibody dynamic model is developed which reflects the experimental results observed in the handrail system of an escalator. Certain model inputs such as non-linear rotational and longitudinal spring coefficients of the handrail and friction coefficient-slip ratio curve of the handrail drive are determined empirically from experimental measurements. The dynamic model effectively explains dynamic characteristics measured in the escalator with respect to various handrail tensions and retarding force. The model has been validated through comparison of experimental and simulated results such as slip ratio, power consumption and vibration of the handrail. The statistical design analysis, response surface method, is applied to determine the vital factors and their optimized levels to improve performance of the escalator. The developed model and its simulation results are used rigorously for design of the escalator handrail system.
